Lets start the week with a quick tip.
Lets say you have a list of employees and their birthdays. Now you want to sort this list, based on their birthday, not age. How would you do it?
Sorting by day and month alone:
- Add a column next to original dates. Lets call this Birthday.
- Then, calculate birthday in current year for everyone.
- Assuming DOB is in B1, Formula for birthday (in current year) would be,
=DATE(YEAR(TODAY()),MONTH(B2),DAY(B2)) - This formula gives you a date which has same year as TODAY(), same month & day as original date.
- Then, fill down the formula for all rows.
- Now sort this new column (Birthday) in chronological order.
- You are done!

Note: if you are using tables, then use this formula.
(Assuming original date is in DOB column),
=DATE(YEAR(TODAY()), MONTH([@DOB]),DAY([@DOB]))

More Sorting Examples:
- Sorting sideways
- Sorting in Olympic medals table style, Formula 1 racing style
- Rounding and sorting data
- Checking if a list is sorted using formulas
- Sorting text values using formulas
Homework for you:
If you think sorting by birthdays is easier than eating a birthday cake, then I have a challenge for you. Assuming a list of data of births is in the range A1:A100, write a formula to find how many birthdays are in this month?

I've just taught yesterday to a colleague of mine how to convert amounts in local currency into another by pasting special the ROE.
great thing to know !!!
Chandoo - this is such a great trick and helps save time. If you don't use this shortcut, you have to take can create a formula where =(ref cell /100), copy that all the way down, covert it to a percentage and then copy/paste values to the original column. This does it all much faster. Nice job!
I was just asking peers yesterday if anyone know if an easy way to do this, I've been editing each cell and adding a % manually vs setting the cell to Percentage for months and just finally reached my wits end. What perfect timing! Thanks, great tip!
If it's just appearance you care about, another alternative is to use this custom number format:
0"%"
By adding the percent sign in quotes, it gets treated as text and won't do what you warned about here: "You can not just format the cells to % format either, excel shows 23 as 2300% then."
Dear Jon S. You are the reason I love the internet. 3 year old comments making my life easier.
Thank you.
Here is a quicker protocol.
Enter 10000% into the extra cell, copy this cell, select the range you need to convert to percentages, and use paste special > divide. Since the Paste > All option is selected, it not only divides by 10000% (i.e. 100), it also applies the % format to the cells being pasted on.
@Martin: That is another very good use of Divide / Multiply operations.
@Tony, @Jody: Thank you 🙂
@Jon S: Good one...
@Jon... now why didnt I think of that.. Excellent
Thank You so much. it is really helped me.
Big help...Thanks
Thanks. That really saved me a lot of time!
Is Show Formulas is turned on in the Formula Ribbon, it will stay in decimal form until that is turned off. Drove me batty for an hour until I just figured it out.
